Kajian Distribusi Spasial Dan Temporar Kadar BOD, TSS dan Oksigen Terlarut (DO) Air Sungai Batang Harau Kota Padang

Abstract

Biological Oxygen Demand (BOD), Total Suspended Solid (TSS), and Dissolved Oxygen (DO) are indicators of water quality in water bodies. Non-polluted water has low BOD and TSS levels and high DO. Changes in these three parameters indicate a change in quality. This study aims to look at variations in the levels of BOD, TSS, and DO spatially and temporarily in Batang Arau River, Padang City in 2018. The study was conducted by observing three stations, namely in the upstream, middle, and downstream, and in the morning and evening. The results showed that BOD and TSS levels tended to increase from upstream to downstream, while DO was the opposite. The temporal variation shows that BOD and TSS levels are low in the morning and increase during the day and evening, while DO is the opposite.

Pollution level in Domas coastal waters based on some water quality parameters

“…An organism has a dissolved oxygen (DO) requirement that varies depending on its type, stage, and activity. Fish in a relatively quiet state require less dissolved oxygen than fish when moving or spawning (Muslim et al 2020).…”

Penentuan Status Mutu Kualitas Air Sungai Bidadari Di Kelurahan Juata Kerikil Kota Tarakan

“…Effendi (2003) menyatakan bahwa material tersuspensi berupa padatan lumpur, pasir halus, bahan organik dan anorganik sangat mempengaruhi nilai TSS dan kekeruhan. Material tersuspensi yang melampaui batas akan berdampak buruk bagi perairan karena dapat menghambat sinar matahari masuk ke badan air (Muslim et al, 2020). Berdasarkan PP No.…”

Kualitas Limbah Pabrik Penyulingan Daun Cengkeh Di Desa Balibo Kecamatan Kindang Kabupaten Bulukumba

“…Limbah cair khususnya parameter Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD) dan Total Suspended Solid (TSS) dengan konsentrasi yang dihasilkan dari proses penyulingan melibihi standar namun langsung dibuang ke sungai yang menyebabkan kontaminasi air sungai sehingga terjadi kerusakan ekosistem. Materi yang tersuspensi sangat mempengaruhi ekosistem perairan karena dapat menghalangi masuknya cahaya matahari dan menyebabkan tumbuhan produsen lambat berkembang bahkan mati (Adnan et al, 2019, Muslim & Gusti, 2020.…”
